With special rolrrenre to Fig. il it will be Seen that with the swiirh l2 rlowil an shown the vibrator eil-ruit will be completed for continuous lpf-ration ot' tlnl vibrator` independently nl' the magneto or the artnatii'm ol the contarte, ISL-4l. over the liollowintr path:

n practice, the entire System may la arranged as Shown in Fig. L the roupling doriee beingr the only addition to thil anual magneto. The rondurtor l1 may erinnert to the rouplinnr "i8 and the switch l2 and interruptor 155 may be .:omn-rzteil. as Separate pieces of apparatus` as shown. although it is obvious that tlnee may be combined in one 'unit It will he further observed that re- 7reresal of the wires at the magneto or be- /tween an)r of the various pieces of appa ratus will have no effect on the. operation ot the system, it being necessary merely to place the. magneto switeln interruptor and battery in series.

In operation, the switch 12 being Closed, th'e interruptor eirenit is completed over the following path: battery l5, vibrator 13, switch 12. conductor 1l, coupling 28, contarts lil-4l, through ground 16 and haelt to battery l5. The dynamo shaft bring;r -slowly turned over as: is the nase when starting, the eontarts lil-2) are separatei'l at the proper time. thnf,v openingthe shunt between the conductor 11 and ground 16 and permitting the interrupted current to [low through the primary winding #L over the circuit previously described. This interrupted eurrent in the. prima r windingv induces a our rent in the seroudaiv winding 5 which produces' a continuous. train oi' sparks at the spark plug .fi as louer as the -rontaets lil-fr remain open. lt will be aren-that the inter'- rupter 13 nrwrates eoutinunusly regardless of \\'l'1ethertlu f contarts 19,-!) are opened or closed but that the opening and (losing ot' Said contacts determine the time at Whioh the spari-z ia proi'lueml at (i, so that the timing of' the Spark, in starting on battery, may be efl'ertrd br adjustment. o-F th'r mining.: il in the Same manner an wbru the magnet-I alone is userlvt'or ignition.
